T0 all whom it may concer/a.'

Be it known that I, Dn'rnnr ILHJOEHNGK, a citizen of the UnitedStates,"residing at Rocky Ford, in the county of Otero vand State ofColorado, haveinvented certain new land useful Improvements in Conveyersand Separators; and I do hereby declare the following to be a full,clear, and exact ydescription of the invention, such as will enableothers skilled in the art'to which it apper-V tains to make and use thesame. Y

My present invention relates `to improvements for `handling articlesthat are to be unloaded from wagons and raised toy a higher elevation sothat they may be dumped into a railroad car, an elevated conveyer, orinto a pile, stack, bin or pit, where such The apparatus hereinafterdescribed may be adapted for the transfer of sugarbeets, tubers, coalstone, grain, or other similar material.

T e invention, however, is j especially adaptedy for luse in connectionwith the transfer of beets, tubers, or other material to which thereisalways more or less dirt or trash attacherLYand from which it isdesirable to remove such foreign matter as far as practicable. f

The invention is especially adapted to the handling of beets, ink whichis is ycustomary to haul them to Cars for,l transportation. i kIt isnecessary to weigh them and as such product contains more or less earth,trash, leaves and foreign matter, it is desirable to screen suoli beetsbefore transporting'them to the factory,rthereby saving transportationof undesirable material and yalso removing such foreign material. YFurther, it is desirable to place in storage Afor future use andshipment a certain quantity Vof raw material to bey used in laterprocess of manufacture. vrFor this purpose the apparatus is especiallyadapted as it may beused to pile material ,atj considerable height andthe app paratus moved from place to place with ease r Vand thereby pileor store anV unlimited Aamount of `material at exceedingly-small eX-pense. y Y. f

Furthermore, the apparatusis adapted to take` care of the loose dirt ortrash that falls from the beets and to carry it away, prefer- .ably inthe kempty carts or cars fromwhich the beets have been fedtoftheapparatus.

This dirt' ,may `accunnilafn in Qbjectonabl@ Vso as to build up a largepile without the necessity for spreading the beets onthe pile manually.

Various other objectsof the present invention will be more fullyunderstood after reference to the accompanying drawings, in whichsimilar'parts are indicated by similar reference symbols throughout theseveral views, and in which Figure l shows va side elevation of thecomplete apparatuaone of the supports for the cart tilting apparatusbeing broken away for the sakeJ of clearness in the drawings.

A represents the main frame supported on the front wheel B and rearwheels B. These wheels are preferably mounted in swivel bearings so thatthe wheels may be turned like a caster :tor steering and guiding themain frame and the parts carried thereby.

Thus, referring to Figs. 1, 2, 10 and 11, T have shown the front wheel Bcarried by an axle 7), whose ends are journaled in the bearings cbeneath the flange ring C which engages beneath an inwardlyprojectingannular flange of the supporting ring D, which is preferably -shaped incross sec tion, and is secured to the main trame A.

The wheels B are similarly mounted on the axles journaled beneath therings carried by the laterally projecting brackets or frames B2, asshown in Figs. 1 and 2.

The axes ot these wheels may be shifted through an angle horizontally inany convenient way, and suitable anti-friction bearings, not shown, maybe provided between the flanges ot the rings C and D, or thecorresponding supports t'or the rear wheels, but l have not deemed itnecessary to complicate the specification or drawings by illustratingthese details.

Mounted above the main frame A, near its forward end, are two tables FJ,which may be in the form of metal plates, or preferably wood faced withwear plates c, as shown in Figs. 10 and 13. Beneath these tables Tprovide a series of racks engaginovpinions F mounted on the shaft' f.This shaft is provided with a ratchet wheel F, which may be turned bythe spring pawl j" carried by the hand Alever F2, but instead ofrotating this shaft by hand it may be rotated by power it desired.

Fach table E has supporting blocks co, see Fig. 10, which rest on theside beams ot the conveyer, as will be hereinafter described, and eachtable may be held against longitudinal movement by rods F/ which passthrough eye-bolts e2 carried by the table and through eye-bolts LOcarried by the side bars h ot the conveyer iframe H, see Fig. 13. YThese rods have upwardly projecting ends t3 which serve as supports forthe directing board FP, see Fig. 3, for purposes that will behereinafter described.

Gr represents the main conveyer on which the beets or other articles tobe separated are dumped trom the wagons, cars, or other vehicles used intransporting same. This conveyor is in the form of an endless apronpassing over the drum AG near the front end ot' the main trame, as shownmost clearly in Figs. 1, 2 and 10. The apron is tightened by anysuitable adjusting means G", see Fig. 10, and passes beneath the idler gand above the cylindrical rollers g2, thence beneath the idler g',whence it travels over the double cone rollers g4, see Figs. 1, 4c and14.

These rollers permit the belt to sag in the middle to torni a trough, asshown in Fig. 1st, the belt traveling between the side bars it of theconveyor trames H and H. The conveyor belt then passes over the upperdrum G2, carried by the upper end ot the coiiveyer trame H, and thenabove suitable guide rollers g3 back to the forward drum G. T he drum u2is mounted on the shaft go which carries the driving pulley C-x3,

which is driven as will be hereinafter described.

The conveyer iti-ame is composed of two members, the lower member Hbeing secured to the main trame beneath the tables E, and the uppermember H of the conveyer trame being hinged like a. deriick so that thismember l'l may be swung up or down through a limited angle, as may bedesired.

The Ytraine is raised or lowered by means et the cables i, see Figs. 1and l, connected to any suitable hoist-ing mechanism not shown. f

'in order to take the strain oit the cables T, l provide an adjustablestrut consisting orn the telescopic members d and J, which may beclamped at the desired position by means or' the set screws y'.

At the upper end of the conveyer frame H T provide a secondary trame H2in which is mounted the shaft /lo ot' the grid screen K, having itssides formed with plates 7c, The cross bar 7c at the rear end et thisgrid is adj ustably suspended by the rods 7a2 screw-threaded at theupper end to engage a nut 7c3 resting upon the cross piece if carried bythe arms H3 projecting rearward troni the conveyor trame ll.

B y screwing u) or easing cilg on these nuts 7a3, the inclination of thegridi'nay be varied within desired limits.

At the bottom of the grid i provide a Lio vley's g4, all as shown inFig. 8.

canvas sampling chute L, which normallyy swings out of the way, as shownin Fig. 4, and whichmay be raised by means of the arm Z and' rod L,seevFig. l, so as to conduct a suitable :amount of the material beingtreated into the receptacle L2, such portion providing :samples ofmaterial handled after screening. f Thedirt and other foreign Vmat terfalling through the inclined grid K is deflected to one side ,or theother of the inclined V-shaped hood N, by means of Vone or the othery ofthe deflecting plates or apron M or M', see Fig. 6. Thereare two ofthese deflecting plates or apron hinged together, as at m, and connectedto the pulley m which travels in the slotted cross bar H? carried by theconveyer frame, and the said pulley may be drawn to one side or theother by means of the hauling lines M2 or M3.

When the pulley m is drawn to the right, the -deiecting plate M deflectsthe'fdirt yto the inclined face a of the hood N, asshown in full linesin Fig. 6, and if the pulley be drawn to the opposite side of the frame,as indicatedk in dotted lines in Fig. G, the dirt will then be deflectedto rthe inclined face n2 of the hood N. Y l At each side of the hood Iprovide endless conveyers Pand P, which receive the .dirt and carry itabove theadjustable dumping platform E, so that it may be dumped intoythe carts, wagons, or -cars ateither side of said platform and carriedaway, as will be hereinafter described.

At their rear ends thesepconveyers P and VP are provided with belttightening arrangements P", and at their front ends these conveyersarepivoted on the axle P2, and each conveyer passes over a drum P3 faston said shaft P2. f This shaft is drivenby the pulley PF, as will behereinafter described.

These conveyers dump the dirt'from the upper ends intofthe hopper' Q.The bottom of this hopper in theform of an inverted Vgsee Fig. 8, andthe hopper is provided with two oppositely-disposed pockets g and gwhich are normally closed by the doors Q, hinged attheirbottms as at gto the Y hopper, which doors may be drawnup by the ropes or chains g3,passing over the pul- So as to prevent thel doors from swinging down toofar, and to enable the doors to Constitute a chute as illustrated indotted lines at the right of Fig. 8,'I provide projecting lugs "g2 attherear V,of each door,which enf gage beneath the bottomy of 4the hopperwhen 'the doorv is'swungl tothe open position ras shown in 8, and thusthese doors serve as chutes to guide the rdirt into tliewagons, j

' *presumed to have been emptied andfready as shown in Fig.

f The three conveyers G, P and P niay be 'driven by means4 ofa'singlecable or rope R, see Fig. passing over the driving pulley R',thence over the pulley P4 for driving the dirt conveyers P and P, thenceunder and over the idler R2, back to the pulley G2 for driving theconveyer'Gr,'thence over the idler R3 under the weighted pulley R4,which keeps the cable under tension, thence over the pulley R5, back tothe driving pulley R. This driving pulley R is driven in any convenientway and by any suitable source of power.

I have shown, in Fig. l, an electric motor S driving the pulley S',which drives the pulley' R0 fast on the same shaft with the drivingpulley R. Inl order to conveniently feed the products to be treated tothe feed tables E and to usethe same power apparatus for this purpose asis used in driving the several conveyers hereinbefo-re referred to, Iprovide apparatus which 1will be hereinafter doscribed, with specialreference to Figs. 1, 2, 3, 3a, 3b and 8.

There are two frames T adapted to be mounted on opposite sides ofthefeed table,

lwhich frames are mounted on pedestals t f shaft U, which shaft carriesa winding drum VU von which the rope or cable U0 is wound.

There is one of these shafts U at each side of the apparatus, whichshaft is connected at its inner ends by the univers-al joint u to thestub shaft U2, carrying the bevel gear U3 and the clutch members u2controlled by the leverV a3 and the rope a4. These stub shafts U2 arealso provided with band brakes U4 operated by rthe levers c45 andropes'u, as shown in Figs. y3 to 3b.

These several ropes pass through leads in a control board Z, so that allmay be. operated from the wagons as they drive up.

The bevel gears U3 are normally loose on the corresponding stub shaftU2, unless connected thereto by the clutch mechanism just tate bypulling on one or the other of the repesy usfsee Fig. 3, and thecorresponding -'rope*U will be'wound up, tilting thewagon body` W of thevcorresponding wagon W, as 'shownto the-right of Fig. 3. The )oppositewagon shown in Fig. 3 is to receive such dirt as has accumulated in llOdown so that the load in the wagon may be conveniently dumped on theadjustable feed table E.

X represents canvas apron adapted to be connected to the wagon, and tothe directing boards El, and into which the fine dirt from the bottom ofthe wagon will fall through Vthe crack next the open side.

The operation of the complete apparatus is as follows rIhe wagons aredriven up opposite the feed tables l, the rope U0 is hooked beneath thebody of the wagon at one side, the opposite side of the wagon is letdown, and the wagon is tilted. as shown t-o the right of F ig. 3. Thecontents of the wagon will be dumped on the feed floor, and the speedwith which the load falls on the conveyer G will be determined by thesize of the throat or opening between the two oppositely disposedsliding tables E. l

As the conveyer apron G passes beyond the frame l-l and reaches theframe l-l, its centre will sag down on the V -shaped rollers gt, forminga trough toward the center of which the beets or other products beingtreated will tend to settle by gravity. As the beets reach the upper endof the conveyer frame H they will be dumped from the conveyer on to thegrid K, and will fall on the pile in the process of being formed, orsamples may be selected from the sampling chute L.

rl`he dirt falling through the grid will be directed to one or the otherof the dirt conveyers P Orl and will be carried upward and dumped intoone side or the other of the hopper Q according to the position of thedefiecting plates or apron M and M. rEhe dirt accumulating in the hopperQ, may be dumped into one of the wagons which has just been emptied, ashereinbefore described, and carried bach to the field, or other placewhere it is desired to deposit same. rlhis dirt may be released from thehopper by simply easing up on the corresponding rope Q3, and the weightof the dirt on the door will swing the same from the closed to the openposition as shown to the right of Fig. S.

T he wagons are driven up into the spaces between the feed table E andthe frame T.

When it is desired to move the apparatus for any reason, as from thegrowth of the lpile to which the products have been Yapplied, the mainframe A may be moved to the desired position traveling on the wheels B,andthe frames 'l may also be moved along at the same time.

By having the ball and socket bearing for the shaft U at the top of eachframe T, and also having the inner end of the said shaft connected toits corresponding stub shaft by a universal joint, it will not benecessary to have the shaft U in exact alinement with the w. 'lineairecorresponding stub shaft U2 and great flexibility of parts is secured.liVhen it is desired to move the apparatus for any considerable distancethe shafts ll will be entirely dismounted and moved separate from theframes T.

rlhe main frame may be moved by a tractor, or by any suitable power, butl have shown in Fig. l a winch Y, driven by the motive power of theapparatus, to which a cable may be attached, and the cable may beconnected to a stub-post, or other Xed body, and the wheels being set tothe desired position, the main frame A may be moved in the desireddirection by rotating this winch, as is well known in the use of dredgeboats for digging canals, etc.

lt willV thus be seen that l provide in a single apparatus means fordumping the wagons, for adjusting the feed to the elevater, forelevating the products, separating the dirt and foreign matter fromsame, and carrying this dirt and foreign matter back to a hopper locatedabove the wagons by means of which from time to time the accumulateddirt may be dumped into an empty wagon and removed.

lt will be obvious that various modifications might be made in theherein described apparatus, and in the construction, combination andarrangement of parts which could be used without departing from thespirit ofA my invention, and l do not mean to limit the invention tosuch details except as particularly pointed out in the claims.

Having thus described my invention what l claim and desire to secure byLetters Patent of the United States is 1.
